Figure 1, we prefer to locate the main air conduit beneath and to the rear of the chairs so the connections leading therefrom, which will be hereinafter referred to and which pass through the floor, will not 1irevent i'ree movement of the attendants Vabout the chairs.

The main air conduit 1 at one end thereof is closed by a cap l and at its opposite end said air conduit is connected to a blower' housing `l within which the usual blower 5 is arranged. The blower housing -l is provided with an inlet opening ti and a discnarge opening T, the last mentioned opening being in communication with the interior of the air conduit 1. S designates a housing which is associated with the blower housingl 1l, said housingl S having located therein an electric motor, or other suitable power generating means 9, by which the blower 5 is actuated.

At points located immediately adjacent to the chairs A the main air conduit 1 is provided with nipples 10 which communicate with the interior of the air conduit and extend upwardly through the floor D (Figure 2), there being one of these nipples at cach chair and said nipples extending through the floor at points beneath and to the rear of the chairs A. Connected to each of the nipples 10 is a liexible air conductor which comprises a single tube sect-ion 11 from which a pair of tube sections 12 branch outwardly, each of said tube sections 12 at the end thereof remote from the end which is connected to the single tube section 11 having an air discharge element 13 connected thereto. The air discharge elements 13 include each a perforated 'all 1l through which air passes.

The discharge element 13 associated with cach of the tube sections 12 is connected lo an arm B of the chair A with which it is associated by means of a suitable clip 15, the particular clip illustrated. in the drawing comprising a spring clamping' element 1li which embraces an arm of the associated. chan' as illustrated in Figure3,and said spring clamping element being connected to the aii discharge element 13 by a swivel joint produced by au extension 17 on the portion 18 of thc air discharge element, which extension is disposed in a recess formed in the member 19 extended upwardly from the spring clamping element 16. 20 designates a set screw which passes through an aperture formed in the member 19, the inner end of said set screw being extended int-o an annular groove 21 fornied in the circumferential face of the extension 17 so as to prevent vertical displacement of said extension with respect to the member 19.

In view of the construction and arrangement of the clips 15 it is plain when the set screws 20 are unscrewed that the air discharge elements 13 may be swung in an ai' of a circle about the verticallyvdisposed axes o the extensions 17,' hence air discharged from said elements 13 may be directed in various directions. It is likewise obvious that the spring clamping elements 16 may be moved longitudinally of the arms B of the chairs to locate the discharge elements 13 in various positions on said arms.

In the use of ouil improved cooling system air discharged by the blower 5 into and through the main air conduit 1 will pass through the flexible air conductors associated with the various chairs A, and because of the location ofthe discharge elements 13 on the arms B of the chairs A said air will be directed by said discharge elements beneath the cloth throws by which the persons occupying the chairs are partially covered, said cloth throws also enclosingl the arms of the chairs and the air discharge elements 13. In view of the arrangement just described the air beneath the cloth throws draped about the pei'- sons in the chairs A will be maintained in circulation thus preventing said persons from becoming uncomfortably warm. As already described the air discharge elements 13 are completely adjustable hence the persons occupying the chairs may move said air discharge elements so as to direct air therefrom as desired.

Each of the nipples 10 is provided with a valve 22 whereby passage of air to the air discharge elements 13 may be regulated and cut off as desired.

An important feature of the invention resides in the face that the flexible conductors leading from the main air conduit to the chairs A permits free movement of the chaii's as desired.

We claim:

1. A cooling system for barber shops and like establishments provided with chairs for persons receiving attention, comprising a main air conduit, means for causing aii to pass through said main air conduit, afflexiblc air conductor leading from said main air couduit and having branch portions leading to opposite sides of a chair, air discharge elements at the discharge ends of the branch portions of said flexible air conductor. and means for adjustably securing said discharge elements to portions of said chair. y

2. A cooling system for barber' shops and like establishments provided with chairs for persons receiving attention, comprising a main aii conduit, means for causing air to pass through said main air conduit, a flexible air conductor leading from said main air conduit and having branch portions leading to opposite sides of a chair, air discharge elements at the discharge ends of the branch portions of said flexible air conductor, and means for adjustably securing said discharge elements to the arm portions of said Chair.

n 3. A cooling system for barber shops and like establishments provided with chairs for persons receiving attention, comprising a our hands.
